Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a paper piece supply device that can be used in the case of binding a paper bundle in which a plurality of papers are laminated.
[0002]
[Prior art]
Paper such as advertising paper is sent to the delivery stage through processes such as printing, folding, trimming, laminating, bundling with resin bands, etc., but conventionally, a series of processes after the above folding process is automatically performed In addition, a processing device for folding and binding signatures is known (see Japanese Patent Application No. 5-140864).
[0003]
As shown in FIG. 9, this folding and binding processing apparatus feeds paper (such as advertising paper) continuously fed in a folded state from a rotary press or a folding machine (both not shown) from a paper feeding unit A. A small bundle is taken into the small bundle stacking section B in the apparatus, and a predetermined number of sheets are stacked in a small bundle state in this small bundle stacking section B, and then this small bundle is sent to the edge cutting section C to cut and remove the creases (mutual origami pieces And then feeding the large bundles into the large bundle stacking section D while reversing the front and rear direction of the small bundles one by one. Here, a predetermined number of small bundles are collected and stacked into large bundles. After being sent to the binding portion E, the binding portion E is used to bind the entire large bundle with a resin band or the like and carry it out of the apparatus.
[0004]
Note that there is a type that does not include the trimming portion C in the processing device for binding the signatures.
By the way, in the binding unit E of the processing apparatus for binding a signature, a binding work table F for supporting a large bundle is provided. Further, before the large bundle is carried into the binding work table F, that is, a large bundle. The paper is supplied so that it becomes the lowermost part (bottom surface) of the paper, or immediately after the large bundle is carried in and before being bundled, that is, the paper is supplied so that it is the uppermost part (upper surface) of the large bundle The paper supply device G is attached.
[0005]
[Problems to be solved by the invention]
Conventionally, when operating the above-described processing for binding signatures, it is sometimes required to insert display paper indicating a delivery destination on the uppermost surface of the large bundle (upper side of the upper side paper). .
In such a case, after the top sheet is supplied to the large bundle, the operator replenishes the display sheet on the top sheet, and then performs the binding operation. It was.
[0006]
That is, as a signature binding processing device, it is necessary to have a worker resident at a predetermined position to intervene manual work only for inserting the display paper in spite of the fact that the folding process and a series of processes are automated. there were.
In order to solve this problem, if a new supply device dedicated to display paper is provided, it will lead to an increase in size and complexity of the paper supply device G as well as the signature binding processing device. I wanted to avoid it if possible.
[0007]
The present invention has been made in view of the above circumstances, and as a paper piece supply device that is incorporated into a processing device for binding a signature or the like and independently configured, not only the supply of paper, but also the supply of display paper It is an object of the present invention to provide a paper piece supply apparatus that can eliminate the need for manual intervention by suppressing the increase in size and complexity of the apparatus.
[0008]
[Means for Solving the Problems]
In the present invention, in order to achieve the above object, the following technical means are taken.
In other words, the paper piece supply apparatus according to the present invention has a paper supply means and a display paper supply means.
Here, the “paper supply means” refers to a basic operation of supplying paper to the lowermost and uppermost parts of a paper bundle in which a plurality of papers are stacked (whether it is a small bundle or a large bundle). The construction is substantially the same as that of a conventional paper supply apparatus. On the other hand, the display paper supply means supplies the display paper onto the paper after the paper supply means supplies the paper to the top of the paper bundle.
[0009]
In such a paper piece supply apparatus, in order to suppress the overall size and complexity associated with the addition of the display paper supply means, the following is preferable.
That is, the paper supply means includes a paper stocker and a cutting means for taking out the paper one by one from the paper stocker and supplying it to the delivery position to the paper bundle.
[0010]
On the other hand, the display paper supply means includes a display paper stocker, and a position changing means that enables the display paper stocker to be replaced with a position where the paper stocker alternates with the cutting means. And
In this way, the display paper supply means is configured to supply the display paper to the delivery position to the paper bundle by using the cutting means provided in the paper supply means as a shared configuration. .
[0011]
Therefore, since the cutting means is shared between the paper supply means and the display paper supply means, the overall size and complexity of the apparatus can be suppressed.
In the display paper supply means, when a turntable is used as the position replacement means, there is an advantage that the position replacement between the display paper stocker and the paper stocker can be performed with a small space and a simple configuration.
[0012]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, a paper piece supply apparatus 1 according to the present invention has a paper supply means X having a paper stocker 2 and a cutting means 3 as a core part of the structure, and includes a display paper stocker 4 and a displacement means 5. The display paper supply means Y which has is provided.
[0013]
The paper supply means X and the display paper supply means Y are obtained by organically combining and integrating the respective constituent members. Therefore, in the following, paper piece supply is performed without distinguishing between them. As a whole of the apparatus 1, the individual components will be described sequentially.
The paper piece supply device 1 shown in the present embodiment is configured in such a manner that the binding unit E of the signature binding processing device shown in FIG. 9 can be replaced with the conventional paper supply device G as it is. The signature binding processing apparatus can be fixed via a fixed base 8.
[0014]
As shown in FIG. 2, the fixed base 8 is formed with a notch-shaped working opening 9 at the center on the side facing the binding portion E (right side in FIG. 2) in a plan view. Is C-shaped. The fixed base 8 is provided with a cutting means 3 so as to be operable in the work opening 9, and a positioning means 5 is provided above the fixed base 8.
[0015]
The position replacement means 5 includes a turntable 13 that is rotatably held in a state where the turning shaft 12 is tilted toward the binding portion E (right side in FIGS. 1 and 2), and the turntable 13 is turned 180 °. And a turning drive unit 14 that can rotate in the forward and reverse directions within the range.
As shown in FIG. 3, in the turntable 13, cutout ports 16 and 17 penetrating in the vertical direction are provided on both sides of the turning shaft 12, and around the openings of the cutout ports 16 and 17. The paper stocker 2 and the display paper stocker 4 are disposed on the enclosed upper surface portion with the turntable 13 as a bottom plate. These stockers 2 and 4 are in a back-to-back positional relationship.
[0016]
As shown in FIG. 2, the turning drive unit 14 of the turntable 13 includes a pinion gear 18 provided on the turning shaft 12, a rack shaft 19 that meshes with the pinion gear 18, and a fluid pressure that drives the rack shaft 19 to move. The thing with the drive tools 20, such as a cylinder, is illustrated. Needless to say, a structure other than this (for example, a structure in which a link mechanism or a gear mechanism is driven by a fluid pressure cylinder, a motor, or the like) can be substituted.
[0017]
The turning range of the turntable 13 is between two positions where the paper stocker 2 and the display paper stocker 4 can be stopped in alignment with the working opening 9 of the fixed base 8, respectively. The positioning is performed by holding the stopper piece 22 (see FIG. 1) attached to the lower surface of the turntable 13 against the restriction pieces 23 provided at symmetrical positions of 180 °.
[0018]
Such a positioning structure uses, for example, a stepping motor or the like as a drive source for turning the turntable 13 and is controlled by the number of input steps, or uses an electric control circuit combined with an appropriate position detection sensor. Can be substituted. In these cases, the turntable 13 may be rotated only in one direction.
[0019]
The paper stocker 2 and the display paper stocker 4 (see FIGS. 1 and 3) described above have the same configuration, and the front wall 24 provided on the outer peripheral side of the turntable 13 and the turning shaft 12 of the turntable 13. It has a back wall 25 provided opposite to the front wall 24 and a pair of left and right side walls 26 provided on both sides in an orthogonal state.
[0020]
The rear wall 25 can be adjusted in the approaching / separating direction with respect to the front wall 24, and the side wall 26 can be adjusted in the approaching / separating direction in the left-right direction.
Thereby, it is possible to cope with the size change of the paper and display paper stored in the paper stocker 2 and the display paper stocker 4.
[0021]
As shown in FIGS. 4 and 5, an opening 28 is provided in the front wall 24 so as to communicate with the cutout openings 16 and 17 of the turntable 13. A gate member 29 having an L-shaped cross section is suspended and held in the opening 28 so that the lower bent piece 29a of the gate member 29 protrudes into the cutouts 16 and 17. (See FIG. 3).
[0022]
Accordingly, the lower bent piece 29a of the gate member 29 is locked to the paper or display paper stored in the paper stocker 2 or the display paper stocker 4, and is suspended from the cutouts 16 and 17, It is possible to prevent companion when one sheet is taken out.
Each gate member 29 is normally in a posture in which the lower bent piece 29a is protruded into each cutout port 16 and 17, but by a driving tool 30 such as a fluid pressure cylinder, each gate member 29 is provided at a predetermined timing. It is possible to retreat to the outside (that is, the escape position from the paper or the display paper).
[0023]
As shown in FIGS. 1 and 2, the cutting means 3 has a pull-out portion 34 and a feed-in portion 35.
As shown in FIGS. 6 and 7, the pull-out portion 34 is configured such that a suction cup 36 provided upward can be swung up and down by a driving tool 38 via a link mechanism 37. As shown in FIG. 3, there are a pair (that is, two) at predetermined intervals in the left-right direction.
[0024]
The suction cup 36 is preferably air-pumped with respect to a vacuuming device (not shown) or the like, depending on the quality of the paper or display paper.
The link mechanism 37 includes a main shaft 42 that is non-rotatably held by fixing both ends to the fixed base 8 by brackets 39, a swing lever 45 that is swingable with respect to the main shaft 42, It has a follower shaft 43 rotatably held on the other end side of the swing lever 45 and a support arm 46 fixed to the follower shaft 43.
[0025]
A suction cup 36 is provided at the upper end of the support arm 46 on the protruding end side, and a hinge portion 47 used for connection with the driving tool 38 is rotatably provided at a lower portion of the support arm 46 near the protruding end. .
Further, the main shaft 42 and the slave shaft 43 are connected to each other by a timing belt 44 via timing pulleys 40 and 41 respectively fixed to them. The relationship between the diameters of the timing pulleys 40 and 41 is such that the timing pulley 40 fixed to the main shaft 42 has a small diameter and the timing pulley 41 fixed to the slave shaft 43 has a large diameter.
[0026]
A fluid pressure cylinder or the like is used for the driving tool 38, and the expansion / contraction operation end side is connected to the hinge portion 47 described above.
For this reason, when the driving tool 38 is extended from the state shown by the solid line in FIG. 6, the support arm 46 is driven by the follower shaft 43 based on the swing locus of the swing lever 45 about the main shaft 42. Is to be moved in a circular arc to the right in FIG.
[0027]
The circular motion of the driven shaft 43 at this time is transmitted from the timing pulley 41 to the timing belt 44 as the rotation of the driven shaft 43 itself, and further transmitted to the timing pulley 40 that cannot rotate together with the main shaft 42. Therefore, the reaction force from the timing pulley 40 acts in the direction in which the driven shaft 43 itself is rotated clockwise.
[0028]
The rotating action of the driven shaft 43 at this time is caused by the difference in the diameters of the timing pulleys 40 and 41, so that the swing angle of the support arm 46 is kept smaller than the swing angle of the swing lever 45. It will be.
As a result, the suction cup 36 swings upward without changing the inclination of the upper surface so much (see the two-dot chain line in FIG. 6). Naturally, after that, when the driving tool 38 is retracted, the above-mentioned operations and actions occur in the opposite directions, and the suction cup 36 does not swing significantly while changing the inclination of the upper surface thereof. To come.
[0029]
The upper limit position when the suction cup 36 is swung up and down is the upper surface level that is the lower side of the inclination in the turntable 13 (that is, in the opening of the cutout opening 16 or 17). The paper stocker 2 or the display paper stocker 4 is brought into contact with the lowest position of the paper or display paper so as to suck it.
As shown in FIG. 1, the feeding portion 35 includes a slide table 51 that is movably held along a guide bar 50 provided on the lower surface of the fixed base 8, and a lower surface level of the fixed base 8 on the slide table 51. And a chuck mechanism 53 provided at the front end portion of the paper receiving plate 52.
[0030]
As a structure for moving the slide table 51, as shown in FIG. 2, a pinion gear device 57 that can be driven by a geared motor 56 with a brake is provided on the fixed base 8, and the pinion gear device 57 is attached to the slide table 51. An example of meshing with a rack rail 58 attached to (not shown in FIG. 2) is shown.
[0031]
Needless to say, this structure can be replaced with a fluid pressure cylinder, a winding transmission structure, a feed screw structure, or the like.
The paper receiving plate 52 moves integrally with the slide table 51, but its lateral dimension is determined so as not to interfere with the suction cup 36 of the pull-out portion 34. The longitudinal dimension is determined so that the paper or display paper can be supported as a whole along the feeding direction.
[0032]
As shown in FIG. 8, the chuck mechanism 53 has a structure in which a clip piece 61 held swingably on a hinge base 60 is driven to swing by a driving tool 62 such as a fluid pressure cylinder or a solenoid. When the clip piece 61 rises and swings in the upward direction by the extending operation, the clip piece 61 sandwiches the paper or display paper (W shown in FIG. 8) with the paper receiving plate 52. ing.
[0033]
The operation status of the paper piece supply apparatus 1 having such a configuration will be described.
In the binding unit E of the signature binding processing apparatus shown in FIG. 9, before the large bundle is carried into the binding work table F, the turntable 13 moves the paper stocker 2 to the binding unit E side (right side of FIG. 1). ). That is, the paper stocker 2 is positioned on the lower side of the slope so as to face the work opening 9 of the fixed base 8 (the position where it meets the cutting means 3).
[0034]
In this state, first, the pull-out portion 34 (see FIG. 6) of the cutting means 3 raises the suction cup 36 to bring the paper at the lowest position of the paper stocker 2 into an adsorbing state. Further, the gate member 29 (see FIGS. 3 and 4) of the paper stocker 2 is opened.
At this time, the chuck mechanism 53 of the feeding portion 35 stands by with the clip piece 61 released.
[0035]
Next, when the drawing portion 34 lowers the suction cup 36 and puts one piece of paper into a half-hanging state, this paper (W) is placed on the paper receiving plate 52 as shown in FIG. The chuck mechanism 53 raises the clip piece 61 and swings it in the upward direction so that the paper is clamped between the paper receiving plate 52 and the paper receiving plate 52.
At this time, the gate member 29 is closed in advance so as to prevent excess paper from being brought together.
[0036]
Thereafter, the feeding unit 35 advances and moves the slide table 51 (see FIG. 1), and conveys a piece of the paper sandwiched by the chuck mechanism 53 toward the binding unit E. In this bundling section E, the press device H waiting above the bundling work table F receives the paper and then lowers it onto the bundling work table F and places it.
[0037]
For this reason, in the feeding unit 35, when the paper is delivered to the press device H, the chuck mechanism 53 releases the paper almost simultaneously with this, and the slide table 51 is quickly returned to the original standby position. It is designed to move back.
In this manner, the paper piece supply device 1 waits for a large bundle to be carried into the binding unit E by the operation on the side of the signature binding processor. When the large bundle is carried in at the binding portion E, the paper taken out onto the binding work table F as described above is supplied (inserted) to the lowermost portion of the large bundle.
[0038]
After that, the paper piece supply device 1 repeats the same operation as described above again, and delivers one sheet of paper to the press device H. As a result, the paper sheet received by the press device H is lowered and placed on the top of the large bundle, so that the paper is also supplied to the top of the large bundle.
Next, in the paper piece supply device 1, the position changing means 5 turns the turntable 13 so that the display paper stocker 4 is positioned on the binding unit E side (right side in FIG. 1). That is, the display paper stocker 4 is positioned on the lower side of the slope so as to face the work opening 9 of the fixed base 8 (the position where it meets the cutting means 3).
[0039]
Thereafter, the paper piece supply device 1 repeats the same operation three times, pulls out the lowest display paper from the display paper stocker 4 and delivers it to the press device H. . In addition, the press device H lowers the received display paper and places it on the upper side of the paper on the large bundle.
After that, the pressing device H applies a pressing force to the large bundle as it is, and the bundling operation at the bundling portion E is executed.
[0040]
By the way, the present invention is not limited to the above embodiment.
For example, as the position replacing means 5, besides the turntable type, a slide method in which the paper stocker 2 and the display paper stocker 4 are arranged side by side along the moving direction on a table that can be linearly moved You can also
Further, as is often used in office copying machines today, it is also possible to employ a mechanism for taking out the paper and display paper from a plurality of types of paper trays through a common path.
[0041]
The present invention may be constructed by attaching display paper supply means Y to the conventional paper supply apparatus G (that is, equivalent to paper supply means X) as a modification, The paper supply means X and the display paper supply means Y may be newly constructed from the beginning as an organic combination.
[0042]
【The invention's effect】
As is clear from the above description, the paper piece supply device according to the present invention has the paper supply means and the display paper supply means, and therefore automatically supplies not only the paper but also the display paper. Yes. This eliminates the need for manual intervention.
In addition, since the display paper supply means uses the cutting means included in the paper supply means, the apparatus can be prevented from being enlarged and complicated.
[0043]
In the display paper supply means, the use of a turntable as the position replacement means can further reduce the space and simplify the structure.
